add listing page

Hi guys,
How would I go about creating a custom add listing page?
What i want to do is have two add-listing pages, one with package1, 2, 3, and the other with package4, 5, 6. I was thinking I can do this by CSS hiding packages on different pages.

So far, added ‘/wp-content/plugins/geodirectory/geodirectory-templates/add-listing.php’
as template (add-listing2), and ‘New Page’ married with add-listing2 template…

A. Is this the best way?

C. If so, how can I choose fields I want to pick up?
i.e. Which page do i need to find .php code? – so i can pick my own fields – or do i have to write from scratch?

Note:
I want both add-listing pages the same essentially, and just hiding fields through price package or CSS. I want different customers using different pages and then have different links in menu etc.
